Abstract
A system including a processor and memory coupled to the processor. The memory is coupled to the processor for storing a local testing database having a test configuration profile with the test configuration profile having an equivalence curve that associates an intensity value with a standardized test result. A lateral flow assay strip reader is coupled to the processor for transmitting an LFA strip image to the processor. The processor determines a standardized test result based on an intensity value of a portion of the LFA strip image using an equivalence curve and provides the standardized test result.
Claims20
A method comprising:
- storing in a memory a local testing database having a test configuration profile with the test configuration profile having an equivalence curve that associates an intensity value with a standardized test result;
- reading a lateral flow assay (“LFA”) strip using an LFA reader coupled to a processor;
- transmitting an LFA strip image to the processor;
- determining a result for the LFA strip image by the processor based on an intensity value of a portion of the LFA strip image using the equivalence curve in the memory.
A method, comprising:
- reading a lateral flow assay (“LFA”) strip, using an imaging device, to generate an LFA strip image including a test line comprising a plurality of columns;
- determining, using a processor, a standardized test result based on an intensity value of a portion of the LFA strip image using an equivalence curve;
- and
- providing, using the processor, the standardized test result.
A method comprising:
- building an equivalence curve for a lateral flow assay (“LFA”) strip, comprising:
- receiving, by a processor, test information for the LFA strip,
- receiving, by the processor, an image of the LFA strip;
- receiving, by the processor, a known concentration of a viral load placed onto the LFA strip;
- associating, by the processor, an intensity of a portion of the image with the known concentration of the viral load placed onto the LFA strip and a standardized value;
- repeating one or more steps, by the processor, until the equivalence curve is created;
- and
- storing the equivalence curve in a memory;
- reading a lateral flow assay (“LFA”) strip, using an imaging device, to generate an LFA strip image including a test line;
- determining, using a processor, a result for the LFA strip image based on an intensity value of a portion of the LFA strip image using the equivalence curve.
